Thing we had to do for school

I am a sick man… I am a spiteful man.
The years have passed me by
Why couldn’t I have made a stand
I lie in bed, wondering why
I am a sick man… I’m a regretful man.
The years have passed me by
All that time I could have ran,
But now it’s too late to fly
I am a sick man… I’m an unhappy man.
The years have passed me by
I could well have saved her life
But I didn’t, and now I die
I am a sick man… I’m a dying man.
The years have passed me by
Now it’s far too late to change
It’s time to say goodbye
